Temperature dependence of spin dynamics near quantum criticality in an Ising ...
This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we plan to use... -
Spin excitations of detwinned BaFe2As2
Although spin excitations in BaFe2As2 are thought spin-wave excitations and the excitation will locate at antiferromagnetic vector (1 0) only for a detwinned sample, the real... -
Two Kondo scales and crystal-field excitations in CeRuSn
At room temperature the ternary stannide CeRuSn crystallizes with a super structure of the monoclinic CeCoAl-type structure. Charge ordering produces a doubling of the unit cell... -
Superconductivity and critical spin fluctuations
In a successful recent experiment on IN5 (ILL), we have been able to show that in contrast to commonly accepted wisdom, the excitation gap in nearly optimally doped...
